Lumber and Timbers Inspection Program
The Northeastern Lumber Manufacturers Association (NELMA) develops and publishes grading rules to assist in the uniform marketing of Northeastern softwood lumber products. (Click here to view a copy of the Standard Grading Rules for Northeastern Lumber). The basis for establishing voluntary softwood lumber standards, including minimum sizes, uniform methods in grading, along with the functions of the American Lumber Standard Committee (ALSC), are provided in the Voluntary Product Standard PS 20-05, developed by the National Institute of Standards and Technology of the U.S. Department of Commence.
